Referring now in detail to the drawing, 10 designates a mop embodyingthe invention. Said mop comprises a head 11, a handle 12 attached tosaid head and a mop element 13 detachably attached to the head.

The head 11 comprises a member 14 which may be made of rigid syntheticplastic material preferably as a molding. Said member 14 comprises afront wall 15 having a downwardly projecting front ange 16. The llange16 has a lower edge 17 and a rear inner surface 18 extending upwardlyfrom the lower edge. At the upper end of the inner surface 18 is arearwardly extending under surface 19 forming a shoulder. Extendingupwardly from the rear end of the surface 19, the front wall 15 isformed with an inner vertical surface 20.

Extending rearwardly from the upper end of the front wall 15 is a topwall 21 from the ends of which extend downwardly a pair of divergingside walls 22. Said side walls also extend to the front wall 15. Theside walls 22 have lower edges 23 and rear edges 24. The rear ends ofthe side walls 22 extend somewhat beyond the rear edge 25 of the topwall 21. Said side walls 22 may be somewhat longitudinally curved asshown in Fig. 9 of the drawing, if desired.

The top wall 21 is formed with a central raisedl portion 26. Said raisedwall 26 is formed with a central opening 27. Said raised wall 26 has arear end edge 28 and inner side walls 29 extending downwardly. Said sidewalls are interconnected by a horizontal shelf 30 spaced below the undersurface 31 of the raised wall 26. The shelf 30 has a rear edge 31 inalignment with the rear edge 25 of the top wall 21 and a front edge 33.The rear end of the top surface of the shelf 30 merges with the rear endof the top surface of the Wall 21. Between the shelf 39 and theunderside of the raised wall 26 is formed a horizontal slot 34, for thepurpose hereinafter appearing.

Extending downwardly from the under side of the top wall 21 on oppositesides of the raised wall 26 are a pair of integral ears 36 formed withaligned through openings 37. The ears 36 are located substantially midway between the front wall 15 and the rear edge`25. The side walls 22are formed with integral inwardly' extending bosses 38 formed withthrough openings 39 aligned with the through openings 37.

Extending through the aligned openings 37, 39 is an elongated hinge pin40. The hinge pin 40 is located below the level of the shaft 30 as shownin Fig. 3 of the drawing. Pivoted to the hinge pin 40 is a rst hingedmember 41 likewise preferably made of rigid, synthetic, plasticmaterial. The member 41 is formed at its front end with forwardlyextending ears 42 substantially contacting the bosses 38 and formed withthrough openings 43 registering and aligned with the openings 39.

Said member 41 is also formed with forwardly extending ears 44substantially contacting the outer sides of ears 36 and formed withthrough openings 45 registering and aligned with the through openings37. The hinge pin 40 passes through openings 43 4and 45 of the ears 42and 44 thereby hinging member 41 to said hinge pin. Member 41 is locatedbetween the side walls 22 and has end edges 47 spaced inwardly of saidvside walls, the ears 42 and 44 of member 41 project downwardly fromsaid member as shown in Fig. 6 of the drawing.

Said member 41 is furthermore formed with rearwardly extending ears 50aligned with the ears` 44 and form-ed with aligned through openings 51.Said member 51 is also formed with rearwardly extending ears 52 yformedwith through' openings 53 aligned with through openings 51. The ears 52are located inwardly of the ears 42 as shown in Fig. 2 of the drawing.Extending through the aligned openings 51, 53 in the ears 52 is ahorizontal elongated hinge pin 54 parallel to the hinge pin 40. Theouter ends of the pin 54 extend beyond the ears 50, for the purposehereinafter appearing. It will be noted that the ears 50, 52 are locatedsubstantially at the rear ends of the side walls 22.

Hinged to the hinged pin 54 is a second hinged member 55 likewisepreferably made of rigid, synthetic, plastic material. Said member 55has forwardly extending ears 56 substantially contacting the outer sideof ears 52 and formed with through openings 57 aligned with openings 53and receiving the outer ends of the hinge pin 54. Said hinge member 55is furthermore formed with a pair of ears 57 substantially contactingthe inner sides of the ears 50 and form-ed with through openings 58aligned and registering with the through openings 51 and through whichthe hinge pin 54 passes.

Said member 55 is formed with notches 60 into which the ears 50, 52project. Said member 55 may furthermore be formed with a plurality ofparallel slots 61 disposed transversely of said member andperpendicularly of the rear edge 62 of said member. Said rear edge 62may be formed with an upwardly extending, reinforcing lip 63, ifdesired. The slots 61 are in two sets or series of slots disposed onopposite sides of the mid portion of member 55, as shown in Figs. 2 andl0 of the drawing. Said m-ember 55 may be furthermore slightlytransversely curved, as shown in Fig. 3.

Said member 55 is formed at its upper side with two aligned pairs ofspaced, upwardly extending apertured ears 64 and 65 located between twosets of slots 61. The ears 64 carry a transverse rivet 66 whereas theears 65 carry a transverse rivet 67. Pivoted to the rivets 66 and 67 andhaving their lower ends received in the slots between the ears 64 and 65are links 68 and 69 interpivoted at their upper ends by a common rivet70. The link 68 has an offset lug 71, for the purpose hereinafterappear- The handle 12 may be made of tubular metal. Its lower end isflattened as at 75 and offset to an angle of about 45 to the handle.Said flattened together portion 75 is formed with a through opening 76.The flattened portion 75 is inserted through the slot 34 and against theunder surface 31 of the raised top wall portion 26 and against the rearsurface of the front wall 15. In such position, the opening 76 willregister or be centralized with the opening 27 in said raised wall 26.It will now be understood that the ilrst swinging member 41 is swingabledownwardly relative to the member 14, and that member 55 may be swungrelative to members 41 and 14. Thus, members 41, 55 may be moved fromthe position shown in Fig. 3 to the position shown in Fig. 4.

To effectuate this swinging movement, there is slidably mounted on thehandle 12, a sleeve 3G having a lower flaring mouth 81. Pivoted to thebottom of the mouth 81 as by a rivet 82 is a connector piece 83.Interconnecting the rivet 70 at the upper end of the links 63, 69 with arivet 84 at the lower end of the connecting member 83, is a connectingrod 85, It will be noted that the rivets 84 and 70 are parallel to oneanother but the rivet 82 is perpendicular to the rivet 84. Thus, theconnector 83 has its upper end twisted to 90 of its lower end, as shownin the drawing.

The mop element 13 is mounted at the under side of the head member 14.Said mop element 13 comprises an adaptor 86 which may be made of wood,plastic or other rigid material. The member 86 is elongated and ofangular cross section and comprises an upwardly extending lange 87 and aforwardly extending ilange 88. The flange 88 contacts the surfaces 18and 19 of the member 14 whereas the flange 87 contacts the rear surfaceof the front wall 15.

Extending through the center of the vertical flange 87 is a verticalscrew 90 having a shank 91 projecting above the adaptor and passingthrough the openings 76 and 27 and thereabove. Said screw has a head atits lower end received in a countersunk opening in the adaptor. A nut 92is screwed to the projecting end of the screw for tightly pressing thcadaptor against the member 14.

Glued or otherwise adhered to the under side of the adaptor is a blockor pad 95 of sponge-like material such as synthetic sponge. The block orpad 95 has a front surface 96 registering with the front edge of thcflange SS. Said pad 95 extends rearwardly of the adaptor S6. The sidewalls 22 of the member 14 are formed with grooves 97 at the lower endsstraddling the block or pad 95. Said pad preferably extends beyond saidopposite side walls 22.

lt will new be understood that the mop element 13 may be removed byunscrewing the nut 92. Mopping is done with the parts in the positionshown in Figs. l and 3. in such position, the sleeve 86 is up. Thehinged elcment 41 is held against the under side of the shelf 30 bymeans of a pair of torsion springs 100 on the pivot pin 40 and disposedbetween the pairs of ears 42, 44.

The member 55 is maintained in the raised position of Figs. 1 and 3 by apair of torsion springs 101 on the pin 54 and located between the pairsof ears 50, 52. In such position, the lug or projection 71 on the link68 contacts the handle 12. Thus, the shelf 30 limits the upward movementof the hinged member 41 whereas the lug 71 lim-tis the upward movementof member 75. Member 41 is located above the rear end of the pad,whereas member 55 is located back of the pad.

To squeeze the water out of the mop block or pad 95, it is merelynecessary to push the sleeve 80 downwardly on the handle 12, therebycausing member 55 to be swung downwardly in a clockwise direction aboutthe hinge pin 54. At the same time, the member 41 is swung downwardlyabout the pin 40, thereby causing the lowering of the hing pin 54. Suchmovement will cause the hinge member 55 to press against the pad 95 andto squeeze it upwardly so as to cause thorough compression of the padfor effectively squeezing water out of the pad. After the squeezingoperation, the sleeve 80 is released, and the torsion springs 100, 101will restore the members 41 and 55 to norm-al raised position. Duringthe squeezing operation, water will squeeze through the slots 61.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved and which is well adaptedto meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.
